BACKGROUND

Many systems exist for delivery of notification messages. They are useful for both business applications (e.g., delivering updates on a software bug tracking system, delivering stock quotes, delivering appointment reminders) and consumer applications (e.g., delivering news updates, delivering sports results, delivering event reminders). In the past, systems delivered reminders either via a push system (e.g., simple mail transfer protocol (SMTP) email transfer, short message service (SMS)) or a user retrieval based system (e.g., feeds using resource description framework site summary (RSS) or Atom format for web feeds). Delivering messages in either of these ways is relatively straightforward, a content provider for a push system needs to maintain a user list and deliver the message to all users; a content provider for a user retrieval system need only publish the messages in a predetermined location using a predetermined format. Modern users demand messages delivered to their mobile smart phones. Different smart phone manufacturers each provide a notification delivery service for their branded phones, each notification delivery service operating using different protocols and different message types, and often provided as a service by the phone manufacturers or phone operating system manufacturers themselves.

In some embodiments, a system for delivering notification messages across different notification media delivers notification messages to a set of users. In some embodiments, the set of users comprises a set of users using smart phones, different subsets of the set of smart phones comprising smart phones using different operating systems (e.g., Apple iPhones, Google Android phones, RIM Blackberry phones, Windows Phone phones, etc.). Each operating system manufacturer maintains a platform notification service specific to the operating system (e.g., Apple maintains an iPhone specific platform notification service; Google maintains an Android specific platform notification service). Each platform notification service can create a new platform notification channel, add subscribers to the platform notification channel, and deliver messages to the subscribers on the platform notification channel. A system for delivering notification messages across different notification media (e.g., a universal notification service) receives a request from a content provider to create a new universal notification channel across different notification platforms. The system requests creation of a new platform notification channel on each platform notification service and maintains a mapping table linking the universal notification channel to the platform notification channels created on each platform notification service. It then provides the set of platform notification channel identifiers to the content provider, so the content provider can advertise them to users. When the content provider wishes to deliver a new content item, it provides the content item to the universal notification service, which uses the mapping table to deliver it to each platform notification service. The platform notification services then deliver the messages to subscribed users of the platform notification channels. In some embodiments, the messages delivered to subscribed users of the platform notification channels are not complete messages but indications of messages, if a user receives an indication of a message and is interested in retrieving the complete message, he may follow an included link or use another mechanism to retrieve the complete message from the content provider.

In some embodiments, the processor of the system is additionally configured to receive a new notification channel indication of the new universal notification channel from the content provider. In some embodiments, the notification channel indication is associated with a subscription request. In some embodiments, the processor is additionally configured to receive a platform notification channel identifier corresponding to the new universal notification channel form each of the one or more platform notification services. In some embodiments, the processor is further configured to receive a new notification handle indication of a new notification handle on the new universal notification channel from the content provider. In some embodiments, the processor is further configured to use the mapping to provide the new notification handle to the one or more platform notification services, wherein the new notification handle is sent to one of the one or more platform notification services through the communication module specific to the one of the one or more platform notification services. In some embodiments, the new notification handle is set to a user using one of the one or more platform notification services. In some embodiments, the new notification handle is used to retrieve a full notification associated with the new notification handle, wherein the full notification is sourced from the content provider. In various embodiments, the full notification is achieved using a link, the full notification is achieved using an application, the full notification is achieve using a web site, or any other appropriate want to achieve the notification. In some embodiments, the platform notification service of the one or more platform notification services comprises a smart phone operating system developer. In various embodiments, smart phone operating system developer comprises an Apple push notification service, an Android push notification service, a Windows Phone push notification service, a Blackberry push notification service, or any other appropriate service. In some embodiments, the mapping uses an identifier for the new universal notification channel.

FIG. 1 is a block diagram illustrating an embodiment of a system for delivering notification messages across different notification media. In the example shown, FIG. 1 comprises network 100. In various embodiments, network 100 comprises one or more of the following: a local area network, a wide area network, a wired network, a wireless network, the Internet, or any other appropriate communication network. In some embodiments, network 100 comprises several different networks that are used for communication between elements of the system. The system comprises content provider 102, universal notification service 104, notification service user 106, platform notification service 108, platform notification service 110, and platform notification service 112 communicate via network 100. Content provider 102 comprises a content provider providing a feed of content to users. For example, content provider 102 comprises an online news service, a reminder service, a business department, or any other appropriate content provider. Content provider 102 comprises a content provider desiring to deliver notification messages across different notification media. Notification service user 106 comprises a notification service user receiving notifications via a notification service. In some embodiments, notification service user 106 comprises a user receiving notifications on a mobile phone (e.g., a smart phone). In some embodiments, notification service user 106 comprises a user receiving notifications from a platform notification service (e.g., one of platform notification service 108, platform notification service 110, and platform notification service 112) specific to the operating system of the user's mobile phone. In some embodiments, notification service user 106 receives notifications via a delivery network. In various embodiments, the delivery network connects notification service user 106 to a wide area network, to a local area network, to the Internet, or to any appropriate network. In some embodiments, the delivery network comprises network 100. In some embodiments, notification service user 106 comprises a user desiring to receive notifications from a content provider (e.g., content provider 102). In various embodiments, there are 1, 100, 222, 1369, or any other appropriate number of notification service users in the system for delivering notification messages across different notification media. In the example shown, platform notification service 108, platform notification service 110, and platform notification service 112 comprise platform notification services for delivering notifications to notification service users (e.g., notification service user 106). For example, each of platform notification service 108, platform notification service 110, and platform notification service 112 comprise platform notification services associated with a smart phone operating system developer (e.g., Apple™ Push Notification Service, Android™ Cloud to Device Messaging Service, Windows™ Phone Push Notification Service, Blackberry™ Push Notification Service, SMS, etc.) for delivering notifications to notification service users using smart phones and using the associated smart phone operating system.

Universal notification service 202 communicates with platform notification service 204. In some embodiments, universal notification service 202 communicates with more than one platform notification service. In various embodiments, universal notification service 202 communicates with platform notification service 204 to request creation of a new platform notification channel, to receive a platform notification channel identifier, to deliver a new notification handle associated with a platform notification channel, or for any other appropriate purpose. Platform notification service 204 communicates with notification service user 206. In some embodiments, platform notification service 204 communicates with more than one notification service user. In various embodiments, platform notification service 204 communicates with notification service user 206 to receive a subscription request, to deliver a new notification handle, or for any other appropriate purpose. Notification service user 206 communicates with content provider 200. In various embodiments, notification service user 206 communicates with content provider 200 to receive a platform notification channel identifier, to request a notification based on a new notification handle, to receive a notification, or for any other appropriate purpose.

FIG. 3 is a block diagram illustrating an embodiment of a universal notification service. In some embodiments, universal notification service 302 comprises universal notification service 104 of FIG. 1. In the example shown, universal notification service 302 communicates with content provider 300 and platform 1 notification service 314 (e.g., a platform notification service for platform 1), platform 2 notification service 316 (e.g., a platform notification service for platform 2), and platform 3 notification service 318 (e.g., a platform notification service for platform 3). Universal notification service 302 comprises controller 304, mapping table 306, platform 1 notification service plugin 308, platform 2 notification service plugin 310, and platform 3 notification service plugin 312. Controller 304 communicates with content provider 300, e.g., to receive a request for a new universal notification channel, to receive a new notification handle, etc. Controller 304 communicates with platform 1 notification service 314, platform 2 notification service 316, and platform 3 notification service 318 via platform 1 notification service plugin 308, platform 2 notification service plugin 310, and platform 3 notification service plugin 312, respectively. A platform notification service plugin (e.g., each of platform 1 notification service plugin 308, platform 2 notification service plugin 310, and platform 3 notification service plugin 312) serves as a communications translator, including all information required for communicating with the associated platform notification service (e.g., platform 1 notification service plugin 308 communicates with platform 1 notification service 314, etc.). Controller 304 delivers messages to each platform notification service plugin (e.g., new platform notification channel messages, new notification handle messages, etc.) and the platform notification service plugin formats the message accordingly and delivers it to its associated notification service according to the appropriate protocol. In the event that a new notification service is added to the system for delivering notification messages across different notification media (e.g., a new smart phone operating system is introduced which the universal notification service needs to deliver notifications to), a new associated platform notification service plugin can be developed and added to universal notification service 302, enabling the system to deliver notifications to the new notification service without changing the operation of controller 304.

When content provider 300 requests a new universal notification channel from universal notification service 302, controller 304 receives the request, generates a universal notification channel ID and in turn requests platform notification channels from each of platform 1 notification service 314, platform 2 notification service 316, and platform 3 notification service 318, via platform 1 notification service plugin 308, platform 2 notification service plugin 310, and platform 3 notification service plugin 312, respectively. Each platform notification service creates the new platform notification channel and returns the platform notification channel ID to universal notification service 302. Controller 304 receives the platform notification channel IDs (via the platform notification service plugins) and creates a mapping from the universal notification channel ID to the received platform notification channel IDs. The mapping is stored in mapping table 306, allowing controller 304 to deliver a new notification handle to the appropriate platform notification channels for a given universal notification channel. Controller 304 additionally delivers the set of platform notification channel IDs to content provider 300, allowing content provider 300 to advertise the platform notification channel Is to notification system users, allowing the notification system user to discover a notification channel on a content provider system (e.g., on a content provider website) and register for the appropriate platform notification channel on the appropriate platform notification service.

FIG. 4 is a diagram illustrating an embodiment of a mapping table. In some embodiments, mapping table 400 comprises mapping table 306 of FIG. 3. In the example, shown, mapping table 400 comprises a set of mappings of universal notification channel IDs to sets of platform notification service IDs. Each universal notification channel ID comprises a content provider identifier (e.g., “Client 1”; “Client 2”; etc.) and a content provider notification channel ID (e.g., “ID 22”; “ID 49”; etc.). In some embodiments, the universal notification service will only deliver notifications received from the content provider associated with the universal notification channel. In some embodiments, the universal notification service will deliver notifications received from any of a set of content providers indicated in the mapping table. In some embodiments, the universal notification service will deliver notifications from any content provider. Corresponding to each universal notification channel ID is a set of platform notification service IDs. Each platform notification service ID corresponds to a platform notification channel on a platform notification service. When a universal notification service controller receives a new notification handle from a content provider on a universal notification channel, it looks up the universal notification channel ID in the mapping table and retrieves the corresponding set of platform notification service IDs. Each notification service ID in the set of platform notification service IDs is sent along with the message handle to the appropriate platform notification service plugin, which communicates a properly formatted message to the associated platform notification service.

In some embodiments, there would be much more data managed in such a table—for example, all kind of housekeeping stuff. In some embodiments, the identifier spaces for the various platforms are different. In some embodiments, the channels would not need to be specific for just a client. In various embodiments, a channel would be open to various clients or even public, so that the user population addressed through that channel could be addressed by more than just one client, or any other appropriate configuration for the channel.

FIG. 5 is a flow diagram illustrating an embodiment of a process for creating a new universal notification channel. In some embodiments, the process of FIG. 5 comprises a process of creating a new universal notification channel on a universal notification service (e.g., universal notification service 104 of FIG. 1) for allowing a content provider (e.g., content provider 102 of FIG. 1) to deliver content to multiple notification service users (e.g., notification service user 106 of FIG. 1) via multiple platform notification services (e.g., platform notification service 108 of FIG. 1, platform notification service 110 of FIG. 1, and platform notification service 112 of FIG. 1). In the example shown, in 500, a new content channel is created. For example, a new content channel is created by a content provider (e.g., an online news service, a reminder service, a business department, an online bug tracking system, etc.). In various embodiments, a new content channel may comprise a news channel (e.g., current results from the French Open, current news about Sudan, etc.), a reminder service channel (e.g., current meeting time updates for the software development group, rehearsal time updates for a theater group, etc.), or any other appropriate new content channel. In 502, a request for a new universal notification channel is sent. For example, a request for a new universal notification channel is sent from the content provider to the universal notification service. In some embodiments, the universal notification channel comprises a distribution channel for the content channel (e.g., the content channel created in 500). In 504, requests for new platform notification channels are sent using platform notification service specific modules. For example, requests for new platform notification channels are sent from the universal notification service to each of the multiple platform notification services (e.g., Apple Push Notification Service, Android Cloud to Device Messaging Service, Windows Push Notification Service, Blackberry Push Notification Service, SMS, etc.). In some embodiments, a platform notification service specific module exists for each platform notification service. In some embodiments, each platform notification service specific module comprises information enabling communication with the platform notification service.

In 506, a new platform notification channel is created and a new notification channel identifier is returned. For example, a new notification channel is created by each of the platform notification services, and the new notification channel identifiers are returned to the universal notification service. The new platform notification channels each correspond to a platform specific version of the universal notification channel (e.g., the universal notification channel requested in 502). In 508, a mapping is created from the new universal notification channel to the new platform notification channel identifiers. For example, a mapping is created by the universal notification service. In some embodiments, a mapping from the new universal notification channel to the new platform notification channel identifiers comprises a correspondence between a new universal notification channel identifier and the new platform notification channel identifiers. In 510, the new mapping entry is added to a mapping table. For example, the new mapping is added to the mapping table by the universal notification service. In some embodiments, adding the new mapping to the mapping table allows the universal notification service to retrieve the new platform notification channel identifiers given the new universal notification channel. In 512, new platform notification channel identifiers are sent. For example, the new platform notification channel identifiers are sent from the universal notification service to the content provider. In 514, new platform notification channel identifiers are associated with the content channel. For example, new platform notification channel identifiers are associated with the content channel by the content provider. In some embodiments, the content channel comprises the content channel created in 500. In some embodiments, associating the new platform notification channel identifiers with the content channel allows the content provider to redirect a user interested in subscribing to the content channel to the appropriate platform notification channel to receive the notifications on his mobile device.

FIG. 6 is a flow diagram illustrating an embodiment of a process for subscribing to a content channel. In some embodiments, the process of FIG. 6 comprises a process of a notification service user (e.g., notification service user 106 of FIG. 1) subscribing to a content channel of a content provider (e.g., content provider 102 of FIG. 1) via a platform notification service (e.g., platform notification service 108 of FIG. 1, platform notification service 110 of FIG. 1, or platform notification service 112 of FIG. 1) In the example shown, in 600, a new content channel is found on a content provider site. For example, a new content channel is found on a content provider site by a notification service user. In various embodiments, a content provider site comprises a content provider website, a content provider smartphone app, a content provider standalone application, an email sent by the content provider, a newsgroup message posted by the content provider, or any other appropriate software or protocol site provided by the content provider. In some embodiments, the notification service user identifies the content channel while browsing the content provider site. In some embodiments, the notification service user navigates to the content provider site in order to find the content channel. In 602, an indication to receive notifications on the new content channel is made. For example, the indication to receive notifications on the new content channel is made by the notification service user. In some embodiments, making an indication to receive notifications on the new content channel comprises clicking a link. In some embodiments, making an indication to receive notifications on the new content channel happens mostly behind the scenes and not visible to a user; there are application programming interfaces (APIs) at work to perform the functionality and, while at some point in time some user interaction might occur, in most cases there is no direct “click on a link” connection. In some embodiments, the content provider site includes a set of links, each link specific to a particular mobile phone operating system. In some embodiments, the content provider site is able to automatically determine the mobile phone operating system in use by the notification service user and interpret the indication appropriately. In some embodiments, making an indication to receive notifications on the new content channel comprises selecting a platform notification channel identifier. In 604, the user is redirected to a platform notification service subscription interface using a platform notification channel identifier. For example, the content provider redirects the user to a platform notification service subscription interface using a platform notification channel identifier. In some embodiments, the platform notification channel identifier comprises a platform notification channel identifier selected in 602. In some embodiments, the platform notification service subscription interface is specific to the mobile phone operating system in use by the notification service user. In 606, a subscription request is sent. For example, a subscription request is sent by the notification service user, using the platform notification service subscription interface. In some embodiments, sending a subscription request registers a user to receive notifications from a platform notification service.

FIG. 7 is a flow diagram illustrating an embodiment of a process for distributing a notification. In some embodiments, the process of FIG. 7 comprises a process for distributing a notification from a content provider (e.g., content provider 102 of FIG. 1) on a universal notification channel on a universal notification service (e.g., universal notification service 104 of FIG. 1) to a notification service user (e.g., notification service user 106 of FIG. 1) via a platform notification service (e.g., platform notification service 108 of FIG. 1, platform notification service 110 of FIG. 1, or platform notification service 112 of FIG. 1). In the example shown, in 700, a notification handle is sent on a universal notification channel. For example, a notification handle is sent by a content provider on an universal notification channel of a universal notification service. In various embodiments, a notification handle comprises an indication of a notification, a link to a notification, a summary of a notification, a notification of a notification, or any other appropriate message allowing a notification service user to retrieve a notification. In 702, the universal notification channel is looked up in the mapping table. For example, the universal notification channel is looked up in the mapping table by the universal notification service. In some embodiments, when the universal notification channel is looked up in the mapping table, platform notification channel identifiers are retrieved. In 704, the notification handle is delivered using platform notification service specific modules. For example, the notification handle is delivered to one or more platform notification services by the universal notification channel, using platform notification service specific modules. In some embodiments, platform notification channel identifiers are used to identify appropriate platform notification channels. In 706, users are notified of the notification handle. For example, users are notified of the notification handle by platform notification services. In some embodiments, notifying a user of a notification handle comprises sending a user a message including a notification handle. In some embodiments, a user can use the notification handle to retrieve an associated full notification, if desired. In some embodiments, the notification handle causes an automated download of the associated full notification.

FIG. 8 is a flow diagram illustrating an embodiment of a process for receiving a notification handle. In some embodiments, the process of FIG. 8 comprises a process for a notification service user (e.g., notification service user 106 of FIG. 1) receiving a notification handle provided by a content provider (e.g., content provider 102 of FIG. 1) on a platform notification service (e.g., platform notification service 108 of FIG. 1, platform notification service 110 of FIG. 1, or platform notification service 112 of FIG. 1). In the example shown, in 800, a notification handle is received. For example, a notification handle is received by a notification service user from a platform notification service. In 802, a notification handle is read. For example, the notification handle is read by a notification service user. In 804, it is determined if there is interest in reading the full notification. For example, it is determined if the notification service user is interested enough in the notification handle to read the associated full notification. If there is not interest in reading the full notification, the process ends. If there is interest in reading the full notification, control passes to 806. In 806, the full notification is retrieved. For example, the full notification is retrieved by the notification service user from the content provider. In various embodiments, the full notification is retrieved by the notification service user from the content provider by clicking a link, executing an application, navigating to a web site, or in any other appropriate way.

FIG. 9 is a flow diagram illustrating an embodiment of a process for delivering notification messages across different notification media. In some embodiments, the process of FIG. 9 is executed by a universal notification service (e.g., universal notification service 104 of FIG. 1). In the example shown, in 900, the universal notification service receives an indication of a new notification channel from a content provider. In 902, the universal notification service provides an indication of the new platform notification channel to one or more platform notification services, wherein the indication is provided to one of the one or more platform notification services through a communication module specific to the one of the one or more platform notification services. In 904, the universal notification service receives a platform notification channel identifier corresponding to the new universal notification channel from each of the one or more platform notification services. In 906, the universal notification service creates a mapping from the new universal notification channel to the set of one or more notification channel identifiers, wherein each platform notification channel identifier of the set of platform notification channel identifiers is received from a platform notification service. In 908, the universal notification service provides the set of one or more platform notification channel identifiers to the content provider of the new universal notification channel. In 910, the universal notification service receives an indication of a new notification handle on the new universal notification channel from the content provider. In 912, the universal notification service uses the mapping to provide the new notification handle to the one or more platform notification services, wherein the new notification handle is sent to one of the one or more platform notification services through the communication module specific to the one of the one or more notification services.
